KCNQ5 (green) is expressed in hilar cells of the hippocampal dentate gyrus. B. Double-staining of KCNQ5 (green) with a neuronal marker (“Milli-Mark” from Millipore, red) reveals partial localization with hilar interneurons (arrow points at an example).

KCNQ genes encode members of the KV7 K+ channels. Structurally, the KCNQ family belongs to the six transmembrane domain category of K+ channels. Five members belong to this family (KCNQ1-KCNQ5) of which KCNQ2 to KCNQ5 are expressed in the nervous system1-3. KCNQ5 is also expressed in visceral smooth muscle4 and skeletal muscle5.
These channels form subunits of the low threshold voltage gated K+ channel. KCNQ2 and KCNQ3 mostly form heteromers to form the M current. KCNQ5 is known to contribute to this current1.

Anti-KCNQ5 Antibody (#APC-155) is a highly specific antibody directed against an epitope of the mouse KV7.5 channel. The antibody can be used in western blot, immunohistochemistry, and immunocytochemistry applications. It has been designed to recognize KCNQ5 from rat, mouse, and human samples.
- Expression of KCNQ1 (KV7.1) and KCNQ5 (KV7.5) in rat smooth muscle cells.Immunocytochemical staining of rat smooth muscle cells from LCA and RCA using Anti-KCNQ1 Antibody (#APC-022) and Anti-KCNQ5 Antibody (#APC-155) shows that the expression of both channels is higher in LCA than in RCA.
